Nobody seems to understand how I feel

I’m feeling so frustrated. My husband and I have been ttc for baby #2 for almost 5 months no success. Everyone that had a baby around the same time as I had our first is pregnant already or had baby #2. It’s so hard ever time another person announces they are pregnant. It’s not that I’m not happy I’m just wanting it to be us. Everyone I have tried to talk to about my feelings says the whole “it will happen when it’s supposed to” thing and it’s not like I don’t know that but it makes me feel like it’s not ok to be sad about it. I feel like I have to keep it in and I can’t express my sadness over it. Does anyone else have this problem or am I just being overly sensitive?
